Currently android.tools.build.gradle is declared in the root build.gradle in the legacy way.

Instead this plugin should be declared in the version catalog. Keep the plugin id in android-tests/build.gradle.

Open question: the version is 7.4.2, there is a more recent version (8.5 at least), but maybe this one is needed for older apiLevel 26. Should we update, it may imply so changes in the android test build declarations.
